Operating Precautions
The Discover® SP-D Clinical System must be grounded. In the event of an electrical short circuit, grounding reduces
the risk of electric shock by providing an escape wire for electrical current. This instrument is equipped with a cord
having a grounding wire with a grounding plug. The plug must be installed into an electrical outlet that is properly
installed and grounded. Consult a qualified electrician or service technician if the grounding instructions are not
completely understood or if doubt exists as to whether the instrument is properly grounded. If it is necessary to use an
extension cord, use only a 3-wire extension cord that has a 3-blade grounding plug and a 3-slot receptacle that will
accept the plug from the instrument. The marked rating of the extension cord must be equal to or greater than the
electrical rating of the instrument.
The possibility of instrument-induced electromagnetic interference (EMI) is minimal if the instrument is operated as outlined
in this manual. The instrument should not be placed close to any electrical device susceptible to EMI. The manufacturer
suggests that the user post a sign warning pacemaker wearers that a microwave device is in operation. If the instrument is
suspected of inducing EMI, a microwave leakage measurement should be performed as outlined in this manual. Any leakage
above the legal limit of 5 mW/cm
2
should be reported to the CEM Service Department.
Cardiac pacemakers require magnets to control their operation during checkout. Because the instrument is equipped
with an electromagnetic sample stirrer which contains very high static magnetic fields, some danger exists if a
pacemaker is positioned in close proximity of the instrument cavity. If the instrument is suspected of interfering with
the operation of a pacemaker, the instrument should be turned off or the pacemaker wearer should move away from
the instrument.
This instrument utilizes high voltages and microwave radiation.
Only those trained in repair and maintenance of
high voltage and microwave power systems should perform instrument service and repair.
Use of the Discover instrument in any manner not specified by CEM Corporation could render the instrument
operation unsafe for the operator.
This instrument complies with United States Code of Federal Regulations 21CFR Part 1030.10 (C) for microwave leakage. A
verification report is on file. This instrument complies with FCC Requirements in the United States Code of Federal
Regulations (47CFR Part 18) Industrial, Scientific and Medical (ISM) Equipment emissions requirements. A verification
report is on file.
